TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 718,390, dated January 13, 1903.

Serial No.11'7,635. (No model.)

To all whom, it may concern:

Be it known that I, ALEXANDER O. SCHU- MAN, of Louisville, in-the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Type- Writing Machines; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in typewriting machines, its object being to provide an improved platen-holdin g carriage for such machines which will enable the platen to be displaced on the carriage when the platen is raised and moved beyond the end of the carriage into position to present the paper on the platen to the action of the printing mechanism of a computing-machine, such as the Burroughs accountant, which may be arranged adjacent to the type-writer, thus enabling an ordinary type-writing machine to be used in conjunction With a computingmachine and the paper-holding platen of the type-writing machine to present the paper in position to receiveimprintfrom the printing mechanism of the calculating-machine.

In the drawings the improvement isshown as applied to the carriage of a Remington type-writer; but I do not restrict myself to such particular application thereof. Further,,in the example shown the platen willbe locked in-proper position relative to the oarriage when the latter is lowered and during the operations of the type-writing machine, but will be thrownupwar'd and remain in vertical position with the platen projected to one 2 designates the paper-carriage, which is substantially like those commonly used on such machines and providedwith grooved wheels 2; running upon the ordinary guiderod 1*. The platen 3 and its turning devices (not shown) are mounted in a frame 3, which is ordinarily connected to the rod 3"; but in the present invention (for the purpose of enabling the platen to be moved farther to one side of the machine or beyond the righthand end of carriage 2) the frame 3 is rigidly connected to a sleeve 3, slidably and rotatably fitted on rod 3 The rod 3 is supported by lugs 4 on a rod 4, which is journaled in end pieces 2 of the carriage, as shown. This enables the platen to be shifted laterally backward and forward on the carriage, as is required on the Remington and other machines where the type-bars carry several characters and the platen is laterally shifted by means of suitable shift-keys when it is desired to print numerals or capitals. The lateral shift of the platen is regulated by opposite screws 2, tapped through lugs 2 on the ends of the carriage, these parts being com monly used in the Remington No. 3 machine and the ends of rod 3 projecting between these lugs, as shown. In order to permit the platen to be moved out to one side of the machine and beyond the end of the carriage, the sleeve 3 is slotted at 3 and when the platen is raised this slot will register with the right-hand lug 4 and allow the platen to be shifted outward to the right and beyond the end of carriage, as indicated in Fig. 2.

To insure that the sleeve 3 may pass out freely between the screws 2, a cam-lug 3 is attached to the sleeve, and a bent rib 2 is attached to the carriage 2, adjacent to lug 3 and when the platen is raised the carriage must first be pushed back until lug 3 engages with flange 2 and prevents the platen shifting too far laterally and stops it, with rod 3 and sleeve 3 lying intermediate the screws 2 as shown in Fig. 3, so that the platen can be moved longitudinally outward beyond the end of the carriage, as indicated in Fig. 2. The sleeve 3 is so long that its right-hand end passes between the screws 2 at the righthand end of carriage 2 before the lug 3 disengages rib 2". When the carriage is in horizontal position,lug 3 will not engage with rib 2 so that these parts do not interfere with the ordinary movements of the platen and carriage.

A computing and printing mechanism 5, such as a Burroughs accountant, is placed beside the type-writer close to the right-hand side thereof, and when the platen-frame is raised to vertical position it can be moved to the right, as indicated in Fig. 2, and will then present the paper in position to receive an impression from the printing-surfaces of the computing mechanism. The type-writer platen thus serves the double function of presenting paper to the type-writer keys and to the computing mechanism, thus enabling the operations of both machines to be recorded on one sheet in proper order and sequence at the will of the operator.

I have simply conventionally indicated the position of such computing mechanism in the drawings, as the particular construction thereof is immaterial and forms no part of presentinvention. Any such mechanism can be used which is provided with that which will make an impression upon the paper on the platen when the latter is in the position shown in Fig. 2.

When the platen is down in horizontal position, the tube 3 cannot slide on rod 3 being prevented by lugs 4; but when the platen is raised, as indicated in Fig. 3, the slot 3 will register with lug 4 and the platen-frame can be moved to the right of the carriage.

The invention can be readily applied to ordinary Remington No. 3 machines with little expense, the paper-carriage and platen shown being in many respects (excepting the sleeve 3,lugs 3 ,andrib 2 substantiallyidentical with the commercial machines now in use; but, as before stated,I do not restrict myself to the Remington machines nor to any particular computing-machine, the underlying feature of the invention being the construction of the typewriter carriage and platen frame in such manner that the platen can be moved beyond the end of its carriage into position to present the paper on the platen to the action of the printing mechanism of an adjacent computing or calculating machine, enabling the operator to use either or both machines independently and at Will take records from either or both machines upon a single sheet of paper on the typewriter platen.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-- 1. In a type-writer, the combination of the longitudinally-movable carriage, the laterally'movable platen-frame thereon, sliding connections between the platen-frame and carriage permitting the platen to be moved longitudinally on and beyond the end of the carriage when lifted, and means for limiting the rearward displacement of the platen-frame when the platen is lifted, substantially as described.

2. In combination, the longitudinally-movable type-writer carriage, the platen-frame, connections between the platen-frame and carriage permitting lateral movement of the platen-frame thereon, and connections between the platen and carriage permittinglongitudinal shifting of the platen on and beyond the end of the carriage, substantially as described.

3. In combination, the longitu dinally-movable type-writer carriage, the platen-frame, connections between the platen-frame and carriage permitting lateral movement of the platen-frame thereon, and connections between the platen and carriage permitting longitudinal shifting of the platen on and beyond the end of the carriage, and means for limiting the rearward movement of the platenframe when raised,substantially as described.

4. In combination, the longitudinally-movable carriage, platen-frame and platen of a type-writing machine, and a sliding connection between the platen-frame and carriage permitting the platen to be moved longitudinally on and beyond the end of the carriage when the platen is raised.

5. In combination, a type-writer carriage, a longitudinal rod thereon, a sleeve on said rod, the platen and the platen-frame connected to said sleeve, whereby the platen when raised can be moved longitudinally on and beyond the end of the carriage.

6. In a typewriter, the combination of the carriage, the laterally-movable rod thereon, the platen-frame slidably mounted on said rod, a ing attached to the platen-frame, and a rib on the carriage engaged by the lug when the platen is raised to prevent further rearward shifting of the platen-frame when raised, substantially as described.

7. In combination, a type-writer carriage, a laterally movable rod thereon, a sleeve mounted on the rod and slotted to permit it to pass the rod-supports when the platen is raised, a platen-frame attached to said sleeve, a platen in said frame, and means for limiting the backward shifting of the frame when the platen is raised, substantially as described.

8. In combination, a longitudinally-movable type-writer carriage, platen, and platenframe, and a connection between the platenframe and the carriage whereby the platen can be moved longitudinally on the carriage, substantially as described.

9. In combination, the carriage of a typewriter, the platen, and platen-frame, a sleeve slidably mounted on the frame-supporting rod of the carriage, said sleeve permitting the platen and frame to he slid longitudinally on the rod and beyond the end of the carriage, substantially as described.

10. In combination the type writer carriage, the laterally-swinging rod attached thereto, the sleeve longitudinally movable on said rod, and the platen-frame attached to the sleeve, substantially as described.

11. In combination, the type writer earriage, the laterally swinging rod attached thereto, the sleeve longitudinally movable on said rod, and the platen-frame attached to the sleeve; With a lug attached to the tube and a rib on the carriage engaged by said lug when the platen-frame is lifted, substantially as described. v
